He did a leak-down test and it's ok so the motor is ok :-)
After a good discussion with John, we are going to replace my K29 turbo by a K27-7200 to have more boost in the lower RPM
Geez, and to think someone wanted to sell you an engine rebuild to fix an oil leak
Why would you throttle that $hit-hot engine with the stock turbo? You won't like the K27-7200, especially in light of the fact that your running a straight K29 now; it runs out of breath at 5k rpm.
I would recommend a K27/K29 hybrid turbo to get the most out of that mill. You get the best of both worlds; the fast spooling of a K27 and to grunt of a K29.

Cobalt: Too bad I did not saw your car, maybe when I'm going to pick mine
I tried to take an appointment since November and get only one in march because of all the delay
but totally worth it
Metal Guru:
Tx for the advice.
John told me that i will have more torque in low RMP than the K29 with the "K27 S"
I also like the idea to go back to some "stockish" motor
Anyway I'm keeping the K29 so i guess it'll be easy to do a K27/K29 hybrid turbo later?
I just need to fix my daughter car seat in the 911 and we should be ready for nice ride this summer
sorry everyone i was lazy and did not updated this thread sooner
So i finally pick up the car from John's place
John just did a fantastic job for a VERY reasonable price
It was a though job because i was missing a lot of small parts for both AC and heating system and the engine is far from stock, so everything is more complicated
For example he has to use a AC compressor for a C2 and not the compressor for a turbo because i have a non stock pulley
He also changed the K29 by a K27 because i like torque in low rpm
At the end of the day, everything is working great and the car still feel very very fast. I'm pretty sure I'm in the 360-400 range
I still have a small leak of oil, he fixed 2 others, and the plan is to bring him the car this winter to drop the motor and see what is exactly in the engine
I found a shop with a dyno 2 minutes away from where I live! I dyno my stock M3 E30 and get 162hp at the wheels :-)
However I prefer to have the last oil leak fixed before dyno my the Porsche but I'll definitively do it
I can't be more happier and i'm strongly recommend John's place for our cars. It's 'far' from long island but definitively worth it
